可见光驱动的氧化锌基光催化剂研究进展

Research Progress of Visible Light-Driven Zinc Oxide-Based Photocatalysts

在光催化领域中倍受青睐的氧化锌(ZnO)具有较强的氧化还原能力、形貌多样易控制、良好的化学稳定性、低成本等优点,但电子空穴复合率高、仅在紫外区进行光催化、易发生光腐蚀等缺点,限制了其在光催化方面的应用。针对以上问题,本文主要从缺陷构建及等离子共振对ZnO光催化活性的影响进行综述,同时对改性方法/使用物质的协同作用进行陈述。最后,对ZnO基光催化剂在可见光下进行光催化反应的未来发展趋势进行了展望。

Zinc oxide (ZnO), which is popular in the field of photocatalysis, has the advantages of strong redox ability, diverse and easy-to-control morphologies, good chemical stability, and low cost. However, the electron-hole recombination rate is high, the photocatalysis occurs only in the ultraviolet region, and ZnO is prone to photocorrosion. These shortcomings limit its application in the photocatalysis field. In view of the above problems, this article mainly reviews the effects of defect construction and plasmon resonance on the photocatalytic activity of ZnO, and also presents the synergy of modification methods/substances used. Finally, the future development trend of photocatalytic reaction of ZnO-based photocatalyst under visible light is forecasted.
